Look, the best thing is to let the plants feed off the substrate for now, and when it starts to run out of nutrients, you can add fertilizers. Wait for the plant to show the first signs of deficiencies before fertilizing. Those 7 liters of substrate will last you at least 1 or 2 more weeks before you need to fertilize. Using fertilizers with every watering or every other watering depends on how concentrated you make the fertilizer; if you want to use it with every watering, then you use it less concentrated.
